DISH-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 643,888, dated February 20, 1900.

Application filed November 6, 1899. Serial No. 736,069. (No model.)

tiac, county of Oakland, State of Michigan, 4

have invented a certain new and useful Improvement in Dish-Washing Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a dish-washing machine, and has for its object improvements in the means employed to thoroughly disperse the water through the dish-chamber.

In the drawings, Figure 1 shows a dishwashing machine in side elevation. Fig. 2 is a plan view of the scattering or dispersing wheel. Fig. 3 is a side elevation of. the scattering or dispersing wheel. Fig. 4 is a perspective of one blade of the dispersing-wheel. Fig. 5 is an elevation showing a connection between the water-pipe and a large tank in which two dispersing-wheels are employed.

In the drawings, A indicates the dish-holding tank, which is preferably square in form and is supported on a framework 13, from which it can be lifted, if desired. At the bottom of the tank is an outlet at for water, and this outlet leads into the bottom of a chamber b, in which reciprocatesa plunger 1). An outlet b leads upward from the bottom of the chamber 1) and has fitted to it a removable pipe that conducts the water back to the dishtank. The removable pipe .may consist of a gooseneck c, which terminates above the tank and leads through the cover 0?. With the gooseneck-tube a there is employed a dispersing or scattering wheel D, whichis of peculiar construction and which is made fast to the under side of the covera just below the opening through the cover into which the gooseneck-tube 0 leads.

The details of the scattering wheel are shown in Figs. 2, 3, and 4. The wheel is held in a hanger d and is journaled on'an axle at. There are several, preferably four, blades to the wheel, and each blade has given to it a peculiar shape and may be for the purpose of explanation considered as divided into four parts, although it is mechanically two pieces of metal, or may even be made of a single piece of metal, if desired. Each blade is soldered or otherwise made secure to a tubular shell e, that constitutes the hub of the wheel. On this tubular shell the main part of the blade 9 stands vertically or nearly vertically,

and near the bottom of the blade the foot f bends abruptly to the left and extends for nearly a quarter of a circle. The surface of the foot f is at an angle to the vertical and at an angle to a horizontal plane, but approaches nearly to a horizontal plane. The extreme edge extends beyond and lies partly under a spur that forms a part of the next preceding blade. The foot f does not touch the spur .9, but between the two there is an opening for water to escape, and after passing off from the foot f the water will strike the oblique portion of the preceding blade. The outer part of the vertical portion 9 of the blade is bent backward, so that the extreme outer edge of the blade angles backward from a plane that extends radially out from the hub. The portion of the blade which is thus bent backward is wider at the top than at the bottom, making the radial boundary-line of the top of the main part 9 of the blade shorter than the radialdistance at the bottom of the blade. This form of wheel when acted upon by the water driven through the pipe 0 rotates with considerable speed and throws the water in every direction, not only sidewise, but directly down beneath it, and scatters it evenly throughout the entire tank below the cover.

In large machines where two wheels are used, as is sometimes the case, the pipe 0 leads to a short horizontal water-chamber 71 each end of which bends downward and terminates with a conductor, below which there is fixed a dispersing-wheel.

What I claim is 1. In a dish-washing machine in combination with a tank and means for delivering water into the tank, a dispersing-wheel provided with vanes having a vertical body g, and oblique foot-plates f, leading in one direction, and spurs leading in the opposite direction; the spurs overlying the forward edge of the blade, and with a spur that extends at the adjacent foot-plate, substantially as dean opposite angle with the main body of the scribed. blade, substantially as described.

2. In a dish-washing machine, in combina- In testimony whereof I sign this specifica 5 tion witha tank and means fordelivering wa- -tion in the presence of two witnesses.
